Wired's Quinn Norton has a great feature in today about amateur clock-hackers who build their own super-accurate atomic clocks. These "Time Nuts" pull stunts like taking their kids hiking in the mountains for a couple days, using their cesium clocks to recreate Einstein's time-gravity experiment to prove that the family had gained 22 nanoseconds on their neighbors by rising high above Earth's gravatic center.
This is just part one -- more tomorrow!
With the end of the Cold War, and with telecommunications technology advancing rapidly, surplus stores and eBay have filled up with discarded precision time equipment once beyond the reach of all but governments. Cesium clocks, rubidium clocks and even the occasional hydrogen maser can be had for less than a decent laptop. A recent search on eBay turned up an HP 5061B cesium standard for sale for $2,000, and you can get a telecom surplus rubidium standard for less than $400. Some of this equipment costs upwards of $50,000 new.
Their access to once-forbidden technology lets the time hackers play in a realm of precision that underpins the modern technological world. A select few, like Van Baak, have started exploring the underpinnings of the universe.
A flashlight review that begins with the promise “I’m about to hike through a remote canyon to an abandoned mine, and I gotta tell you there’s a storm raging outside” should end on an interesting note, and this one does. [via] Disturbing, strange sounds. That’s exactly what I caught on video while filming and documenting […]
Reflectacles, the hyper-reflective Ray Ban-style $75 glasses frames that Scott Urban is Kickstarting have a new feature: now you can get ones doped with materials that reflect the infrared light that CCTVs kick out to let them capture images in low light, which blind cameras’ sensors. Cool!
Typewriter historian Martin Howard (previously) writes, “I was able to pick up a rare and exquisite Waverley typewriter (1896) this summer in Scotland and have just the other day posted it to my website all cleaned and ready to show.”
Loot Crate is a totally different kind of subscription service that mails subscribers monthly boxes filled with curated geek, pop culture, and gamer paraphernalia. Its cult following awaits a box every month filled with everything from bobble heads to T-shirts to special edition collectibles. But nothing gets Loot Crate fans as excited as the limited […]
The ARMOR-X Mini Flexible Phone Tripod is a smartphone tripod that is designed with flexible legs to rest on virtually any type of surface. Other tripods have proved useless unless I conveniently have a flat surface in front of me, which is why this particular tripod was appealing enough to try out. The ARMOR-X is compact and easy […]
You don’t need to get an advanced degree and take out massive loans to become a coder. This bundle of 10 courses was designed to teach anyone to code at home for less than it costs to go out for dinner. I was particularly impressed with this new 2017 bundle because it includes courses on […]
